Create mysql database in another location?

[giavinh]

Hi All,

Normally DirectAdmin stores mysql database in /var/lib/mysql.
Now I want to change my database folder to /data/mysql. I did as following: edit my.cnf and put 'datadir=/data/mysql'

It's seem to be OK but when I go to DirectAdmin "MySQL Management" an error happening: "Error connecting to MySQL: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)"

Then I can't create database via DirectAdmin because of that error.

Can anybody help me?

Thanks all,
Best Regards,

I believe that DirectAdmin is hardcoded and uses linux/unix rules for placement.

If so then the best you can do is create a link; note that doing this could break your server; I take no responsibility for any damage you do:

# rm -rf //var/lib/mysql
# ln -s /data/mysql /var/lib/mysql

Thank you so much jlasman,

I did it, but what you mean for "this could break your server" it is not good to link like this?
I just want to store mysql to another mounted hdd (/data/mysql) to share HDD works with httpd.

Cos I think that if we put all in the same hdd, the hdd will work very hard.

Thanks,

I have done this on redhat based systems with no consequences.

I meant simply that you cannot expect me to take resonsibility for anything you do on your server, even if you believe you're following my advice.

I could make a typographical error in a command and you could delete all your databases.

You could make an error in typing the command and you could delete all your databases.

Since I don't test it before writing it, I could misremember the command and you could delete all your databases.

If you have any databases in the directory you're deleting (why? I have no idea) you'd lose them when you did the delete.

Lots of ways to break your server.

I take full responsibility when you pay me to log in and do it, but if not, then you must take full responsibility.

I hope that's clear, and I hope it's acceptable.
